I got these guys back in December. I started on them but didn't get through them. I had just a few left to finish but hadn't worked on them since then.
I had been mostly focused on the 30K Thousand Sons army I was working on and only picked these up because I liked the figures and they were pretty different from what I was painting at the time.
Going through some stuff I found them and pulled them out a little while before Dark Imperium came out and decided to finish them off a little at a time.
I got a little bit done here and there since I finished off my Primaris marines and now they are all done.
They are about the size of Primaris marines so will be one of the few Chaos forces I have that I'll be fielding against my Ultramarines. The slight difference in size can be put down to the fact that there isn't anyone in this armour and it might have collapsed on itself a little bit or not be quiet as filled out.
I have a unit of Terminators for them too. I bought two boxes at the local store here when they had them marked down to $40. USD
I turned one of the boxes into my Sehkmet Termies for my 30K Thousand Sons but the other ones I built to go with this army. I'll probably start on them in earnest after Historicon is over but right now I'm really only doing stuff for that.
